PESHAWAR: A US drone strike late on Saturday left five suspected militants dead and two others injured in North Waziristan Agency, sources told DawnNews.

It further said that two missiles were fired that hit two houses in Warokey Mandi area of Shawal Tehsil of North Waziristan Agency, a tribal region where the military has since June been battling militants linked to the Taliban and Al-Qaeda.

Meanwhile, official sources claimed that those suspected militants killed in the US drone strike were Uzbek nationals.

The area is generally off-limits to journalists, making it difficult to independently verify the number and identity of the dead.

“The US drone fired two missiles targeting a militant compound, killing four rebels,” a senior security official said on condition of anonymity.
